Abstract:

Moving Objects Databases have become an enabling technology for a variety of applications that require some type of Location Based Services: military, environmental, medical/assisted living, traffic management - to name but a few. However, the management of the large amounts of mobile objects, in addition to the efficient processing of some typical queries (e.g., range, nearest-neighbor), may require other kinds of context-awareness.
In many applications settings, given the current state and the history of the spatio-temporal evolution of the mobile entities, certain activities may need to be undertaken - e.g., increasing the quality of tracking; re-routing of mobile resources, etc. In such cases, in addition to reacting to a particular event (primitive and/or composite) and (pending the condition) executing the corresponding action, the available resources may need to be reorganized and steered towards monitoring different events than the ones in the recent past.
In this talk, we will present several application scenarios and demonstrate that they "converge" in the sense that in all of them it is essential to efficiently detect whether a particular type(s) of spatio-temporal predicate is satisfied. More importantly, the satisfaction of such predicate has subsequent implications on how the application requirements are monitored and managed. In addition to the processing algorithms, we will present a formalism for context-aware management of the reactive behavior with pro-active impacts in such mobile dynamic systems.
